From ead77b65aef430d3bfe63524c243a60a29eb8d90 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Fri, 2 Sep 2022 15:29:24 +0200 Subject: HID: export hid_report_type to uapi When we are dealing with eBPF, we need to have access to the report type. Currently our implementation differs from the USB standard, making it impossible for users to know the exact value besides hardcoding it themselves. And instead of a blank define, convert it as an enum. Note that we need to also do change in the ll_driver API, but given that this will have a wider impact outside of this tree, we leave this as a TODO for the future.
